UL Rated Assembly for High Heat Duct Penetration
Working on a project where we have a flue duct penetrating a 2hr rated wall. This is an insulated duct, but the outside of the insultation can still reach temperatures up to 200 degrees. Is there any UL rated assembly that would insulate and protect the gypsum assembly while standing up to the high temperatures?
